IMPROVED BRICK.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL McLAUGllLIN, of Philadelphia, Pennsylvania,have invented an Improved Brick; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawing, and to the letters of reference markedthereon.

My invention consists of bricks having ribs andgrooves adaptedto eachother, as described hereafter, so that a wall built of these bricks maybe stronger and more permanent than a wall of ordinary bricks.

In order to enable others to make my invention, I will now proceed todescribe the manner of carrying it into effect. On reference to theaccompanying drawing, which forms a part of thisspecification- Figure 1is a plan view of my improved brick.

Figure 2, an end view.

Figure 3, a perspective view of a number of the improved bricks.

Figure 4, a plan view of the improved bricks, as arranged for the cornerof a wall; and

Figure '5, the same with the bricks on edge. I 7

On reference to figs. 1, 2, and 3, A represents the improved brick, onthe upper surface of which, midway,

or thereabouts, between its opposite edges, is formed a longitudinalrib, a. and on the under surface a. longitudinal groove, 6,corresponding, as regards form and position, to the rib above. On oneend of the brick is a vertical rib, c, and at the opposite end avertical groove, 11,, corresponding, as regards form and position, tothe said rib. When bricks thus constructed are laid as shown in fig. 3,so that the longitudinal rib of one brick shall enter the grooves of thebricks above, and the rib at the end of one brick shall fit into thegroove of the adjacent brick, the series of bricks are so intimatelybound together that no lateral displacement of the bricks or distortionof the wall can take place under circumstances which would disturb theintegrity of a wall of ordinary bricks, hence my improved bricks areespecially applicable to the construction of furnace walls, which, owingto the great heat. to which they are subjected, are liableto a rapiddeterioration. For the corner of a wall, as seen in fig. 4, it isnecessary that the brick A should have on one edge a vertical groove at:r, in such a position as to admit the vertical rib c atone end of theadjacent brick A. By this arrangement the corner is rendered mostsubstantial. A very thin and light, but rigid, wall may be made bylaying the bricks on edge, as shown in fig. 5, the ribs and groovesbeing in this case on the edge of the bricks, instead of on the fiatsurface of the same. It will be understood that the grooves may be aboveand the ribs below.

I claim as my invention, and desire to secure by Letters 'Putent- ABricks having ribs and grooves arranged substantially as and for thepurpose herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
